Which polynomial is factored completely

Ket [755]

Answer: The correct option is c.

Explanation:

Reason for correct option:

$3x(9x^2+1)$

This expression cannot be factored further because $(9x^2+1)$ is the complete factor. Therefore the option c is correct.

Reason for incorrect option:

$5x^2-17x+14=5x^2-10x-7x+14=5x(x-2)-7(x-2)=(x-2)(5x-7)$

Since the given expression can be factored further therefore the option d is incorrect.

$4(4x^4-1)=4((2x)^2-1)=4(2x^2-1)(2x^2+1)$

Since the given expression can be factored further. Therefore the option a is incorrect.

$2x(y^3-4y^2+5y)=2xy(y^2-4y+5)$

Since the given expression can be factored further. Therefore the option b is incorrect.

Answer:

${x}^{2} + 4x - 9 = 5x + 3 \\ {x }^{2} - x - 12 \\ {x}^{2} - 4x + 3x - 12 \\ x(x - 4) + 3(x - 4) \\ (x - 4)(x + 3) \\ x = 4 \: and - 3$

Use the formula M = NPQ to solve for the following variables.

Oksanka [162]

Step-by-step explanation:

M=NPQ

m/pq=Npq/pq

pq is going to cancel, you left with N

N= m/pq

To solve for q, we have to make q the subject.

m = Npq

divide both sides of the equation by NP

M/NP= q

that's the answer
